Applicable To
Conditions this code is used for: synonyms of the title or, for "other specified" codes, the conditions assigned to it. The list is not exhaustive.
- Other benign neoplasm of anal margin
- Other benign neoplasm of anal skin
- Other benign neoplasm of perianal skin

Excludes1
Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.
- benign neoplasm of anus NOS (D12.9)
Excludes2
Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.
Notes
General instructions on how these codes are used.
- Functional activity
- All neoplasms are classified in this chapter, whether they are functionally active or not. An additional code from Chapter 4 may be used, to identify functional activity associated with any neoplasm.
- Morphology [Histology]
- Chapter 2 classifies neoplasms primarily by site (topography), with broad groupings for behavior, malignant, in situ, benign, etc. The Table of Neoplasms should be used to identify the correct topography code. In a few cases, such as for malignant melanoma and certain neuroendocrine tumors, the morphology (histologic type) is included in the category and codes.
- Primary malignant neoplasms overlapping site boundaries
- A primary malignant neoplasm that overlaps two or more contiguous (next to each other) sites should be classified to the subcategory/code .8 ('overlapping lesion'), unless the combination is specifically indexed elsewhere. For multiple neoplasms of the same site that are not contiguous, such as tumors in different quadrants of the same breast, codes for each site should be assigned.
- Malignant neoplasm of ectopic tissue
- Malignant neoplasms of ectopic tissue are to be coded to the site mentioned, e.g., ectopic pancreatic malignant neoplasms are coded to pancreas, unspecified (C25.9).

Patient EducationClinical
Benign Tumors
Tumors are abnormal growths in your body. They can be either benign or malignant. Benign tumors aren't cancer. Malignant ones are. Benign tumors grow only in one place. They cannot spread or invade other parts of your body. Even so, they can be dangerous if they press on vital organs, such as your brain.

Questions About D23.5Overview
What is the ICD-10 code for other benign neoplasm of skin of trunk?
The ICD-10-CM code for other benign neoplasm of skin of trunk is D23.5 (sometimes written as D235). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is D23.5 (Other benign neoplasms of skin) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report other benign neoplasm of skin of trunk on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does D23.5 group to?
When other benign neoplasm of skin of trunk is the principal diagnosis on an inpatient stay, it groups to MS-DRG 607, 606, with relative weights from 0.8772 to 1.5721 depending on complications. Higher weights mean higher Medicare reimbursement.
Can D23.5 be reported with D12.9?
Not as a rule. The Excludes1 note on D23.5 lists "benign neoplasm of anus NOS (D12.9)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
What is the ICD-9 equivalent of D23.5?
Under the General Equivalence Mappings, other benign neoplasm of skin of trunk converts to ICD-9-CM 216.5 (benign neo skin trunk). The mapping is approximate, so confirm the match fits the documentation.
